GEORGE R. CLARK, OF DAYTON, OHIO, ASSIGNOR T CLARK & HARVEY, OF DAYTON,OHIO, A PARTNERSHIP COMPOSED OF yGrEO-GEI R. CLARK AND THOMAS J'.HARVEY.

TIME-CONTROLLED OFERATING MECHANISM.

To all whom iti au; y concern Be it known that I, GEORGE R. CLARK, acitizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Time-Controlled Operating Mechanism, of which the usefor the operation of other devices.

An object of the invention is to provide a device `of the character.referred to which is capable of operating electric switches of largecapacity.

A further object of my improvements is to provide means for preventing.the run ning down of the motor mechanism when the lights are on, meansbeing employed for automatically throwing out of operation the operatingdevices at the end of a certain definite period and for maintaining saiddevices out of operative position until the mechanism has been fullyre-wo-und.

A further object of my invention is to provide means for turning thelights on or off at any time b v hand and at the same time forautomatically throwing out of commission the tripping device which, inthe usual course of events, would next cause the operation of the motormechanism; and also to provide means whereupon, at the next operation ofthe machine, this tripping device,y will be restored to normal operativepo sition.

A further object of the invention is to provide 'f'or the setting of thetripping devices to vani-e them to operate al certain predeterminedtimes without ymental calculation upon the part of the operator.4

A further object is to simplify, chea'pen the construction and make moreeffective the operation of devices oi this character.

The invention consists in the construction and combination of partshereinafter described and 'Het forth in the. claims:

Like parts are represented by similar characters voi? reference in theseveral views.

Frame-In the said drawings. l represents a front vertically disposedsupporting frame or plate, and 2 a similarly arranged rear plate,connected together at the top by transverse rods 3 and 4 and beingsecured at the bottom to a lower supporting frame by rods 5 and 6; thislower frame-work heing made up of a base, 7, and upright standards 8 and9.

Tripping dcoz'ccsf-Loosely mounted in the trame parts 1 and 2 isa shaftor arbor b (see Fig. G for detail), which arbor is driven i'rtnr theclock motor spring ii through the medium of the gear, b2, pinion 63.gear b4 and pinion b5. which pinion 7) is fast to the said arbor Zi.' a.gear Ujsecured to said pinion being connected with any suitable andwell-known clock mechanism for controlling the movement ot the clockmotor so as to'cause said arbor to revolve once every l2 hours. A pinionfast to the a1'- bor, drives the gar Zr, loose on said arbor, throughthe medium of the gear b9 and pinthe same. Fig. is a vertical section ofthe 5gg ion b1, the proportion of the gearingbeing such that the gear bswill be caused to revolve once every 24 hours. This gear bs has anenlarged hub b and an extended sleeve I)12 fitted loosely about thearbor. Loosely mounted on the sleeve bn and abutting against theenlarged hub b is a second vsleeve b, carrying at its inner end a cam,

b. Loosely mounted on the sleeve b13 and abutting against a shoulderformed thereon is a third sleeve b, which alsa carries at its inner enda cam, bw. Loosely mounted upon the sleeve b1, is a dial b, graduated intwo sections from 1 to 1.2, which gradu* ations read from right to left,as shown in Fig. 1. This dial, While loose on said sleeve, is adapted tobe clamped thereto through the medium of the collar, b, secured to thesleeve, and nut b1 screwthreaded on the sleeve. Connected to the end ofsaid sleeve 515, which is squared, by a lock washer 52 is an indicatinghandfbzl. Secured to the squared end of the sleeve b13 by the nut b", isa second indicating hand b, said nut being screwed onto the end of thearbor. By the construction described the indicat' g hands, and hence thecams b and, m y be set to the proper position with respect to the dial,and the hands, dial sleeve and gear bs all clamped together so as torevolve once every 24 hours. The particular feature of novelty in thisconstruction is the manner of setting the vhands without the vaid ofymental calculation.

By referring to Fig. 1 it will be observed that the dial 1s divided intotwo series of indications from 1 to 12 inclusive, these in dicationsbeing arranged reversely to the direction of rotation of the dialindicated by the arrow. If the operator wishes to set the mechanismv sothat the lights will be turned on at 5 oclock p. m. and be turned 01T at10 oclock p. m. he first moves the dial so that' one of the indicationsthereon representing the exact hour of the day will 'i come opposite thestationary pointer b,

(Fig. l). For instance, if the time at which he sets the mechanism is 10oclock a. m., he turns the dial -until one of the indications 10 thereonregisters with the stationary pointer b. Then, by causing' the turn-onpointer to register with the first indication 5 and' the turn-offpointerl to 'register with the first indication to the left of pointer10, and then securely fastening the parts together in the manner beforedescribed the mechanism will be properly set to turn on and off thelights atk the proper time de' sired.

`Pivota1ly mounted upon a stud, c, projecting forwardly from the frameart 1, are two trip-arms c and c2, which arms exs tend alongside therespective cams b1* and b" and are normally spring-pressed downwardly'by the coil springs c arranged about the stud c and exertingtheir infiuen'ce on said arms. Each of the arms has a laterallyprojecting pin 0*, shown in dotted lines in Fig. 5, which project overthe respective cams so that as said cams revolve the arms will be raisedand, at the proper time detervmined by the position to which the camshave been set, the pins will ride off of the high points of the camsvand permit the arms to drop by the tension of their springs.

Located in the path of movement of each of the trip-arms is a pivotedpawl e and e', these pawls being each pivoted at one end to a support c2secured to the frame part 1. Extending transversely beneath thesepivoted pawls .is a small cross-bar e* (see Figs. 4, 5, 13 and 15) whichcross-bar is connected to a crank e (Fig. 10) secured to a rotatablelock e located in said frame art e2. This rotatable lock e iscylindrical 1n form and one part thereof is attenfl as indicated at e7in Figs.,13 and 15. .-.xtending vertically through a channel in thissupport c2 is a rod, e, and formed in this rod at a point normallycoincident with the attened portion of the lock e6 is a rounded recess eof a size equal to that of the diameter of the cylindrical lock. Locatedin the support e2 beneath the cross-bar e* is a plunger e10 (Fig. 15)normally spring-pressed by a spring e up against the cross-bar so i asto normally rock the cylindrical lock to the position shown at Fig. 15,in which position the rod e is locked a ainst movement. The lower end ofthis ro is ofl'set and is pivotally connected to the end of an arm e,the oppositeend of said arm being pivoted at e to the frame part 1. Thisarm e has formed thereon a rounded or beveled shoulder e and thisshoulder normally forms, when the rod el is locked, a bar to the motormechanism hereinafter described, but whenever one of thetriparms c or c.is released by its cam this pivoted arm e" will yield to release themotor mec anism by reason of the facttthat the trip-v1 armv operatingupon one of the pawls e or e will rock the cylindrical lock e throughthe medium of the cross-bar and crank and thus unlock or release the rodes.

Motor mechanam--d is .the main-spring! nected to the outer end of saidshaft are two projecting arms d and d* (Fig. 5) and the said shoulder eon the arm e normally stands in the path of movement of the endsof saidarms so as to form a bar therefor,`

roo

hr 11o and hold the shaft at rest. The end of each f of these arms isformed with an inclined surface d which rests against the beveled orinclined art of the said shoulder so that when' the said rodeis'unlocked inithemanner before described the tension of the motorvspring, (l, will cause the arm a14 or di which is in Contact with saidbeveled shoulder to force said pivoted arm cl2 downwardly and thusrelease themotor mechanism, permitting the shaft d? to revolvefor aperiod of one-half revolution. Before the shaft has completed thisone-half revolution, however, the shoulder c14 will again be broughtinto the path of movement of the other arm so as to again form a bar tothe motor mechanism and arrest the same. This is accomplished byproviding two cam-shaped projecl'ions fl and c/T connected to the outerend of said shaft so as to revolve therewith, either one of whichcanrshaped projections. when the shaft is revolved, being adapted tocontact a. pin (Z8 extending laterally from the rod e and thus forcesaid rod upwardly until it is again engaged by the rotatable lock ebefore described. Connected to the rear end of the said shaft (I2 is amutilated bevel gear als. one-half ol' this gear being devoid of teeth.Located in suitable bearings /N secured to the rear frame portion 2 is aloi e'itudinal shaft d which has secured thereto tvo beveled pinions aland d located on either side of the mutilated gear d and adapted to bealternately engaged with the teeth thereof so as to first give saidshaft f7 a movement in one direction by a onehalf revolution of saidmotorshaft d2 and then a movement in the opposite direction upon thenext succeeding of one-half revolution of said shaft d"liocated insuitable guides dit on saiddframe part 2 isa vertical rack /IVf/theteeth0T which are hin Y shaft du. y

one member d" of the switch which member mesh with the pinion (G securedto said The lower end of this rack carries carries preferably fourcontacts om. The other contactingr members d of said switch are locatedon Vthe base 7 of the machine,

four beingy provided. one for each contact d. Each of the cams 1,14 ando16 near the high part thereof is pro-vided with a shoulder c5, whichshoulders cooperate with thtI pins of the `respective trip-arms to prevent any tmt'kward movement of the Cams after the pins have dropped oversaid shoul- 'l`he shoulders are so located that the pins will drop overthem just about the time that the outer ends of the trip-arms pass therespective pawls, e and e', on the upward movement of the trip arms; itbeing understood that these pawls swing freely upward to permit thepassage of said arms on their upwardv movement. The pins having droppedover the shoulders, will form a bar against any backward movement of thecams such as might be caused when the operator is setting the indicatinghands and accidentally permits the devices tomovebackwardly; it beingunderstood that as the hands are set dern and the cams turned, theraising of the arms l ,to throw said trip-arm downwardly.

c and o1 puts their springs under tension and causes the pins c to exerta pressure against the cams, this having a tendency to turn thembackward. It will be understood that if one of the cams is permitted tomove back after its trip-arm had assed the pawl on the upward movement,t is would cause the triparn1 to drop back again and trip the pawl andrelease the motor mechanism and would probably hold the pawl down sothat the mechanism, and hence the switch, would operate continuously.The result of this construction is that each time the motor mechanism isreleased by the devices described the rack d will be operated rapidly upor down to open or close the switch.

H amd-operated trips-It is sometimes desirable to turn the lights on oroff before the regular time or the time at which the mech? anism is set.In order to accomplish this, I have provided a hand-operated device soarranged that the operator can open or close the switch and at'the sametime throw out of commission the trip which would, in the ordinarycourse of events, next be operated; means being further provided, uponthe next operation of the mechanism, to again restore this trip tonormal operative position. This hand-operated device is best illustratedin Figs. 5, 7, 10, l1 andv 15. Rotatably mounted upon a stud whichprojects forwardly from the frame part 1, are two oppositely ar rangedca'ms f and f, each of said cams be.- ing provided with a shoulder f2*to prevent any backward movement of the cam 4for the same purpose asdescribed in connection with the shoulders on the cams c and c. Thesleeve f2 to which these cams are connected has secured at its outer enda knurled finger-piece f3. Located adjacent the cams is a verticallydisposed link or rod f4 provided with a slotted openingf5 to permit saidrod to straddle the stud f upon which the cams are mounted. The upperend of this link is provided with a laterally projecting pin f7 lying inthe path of movement of the cams so that whenever the cams are turned bythe operator this link or rod, f4, will be raised. This link f4 has itslower end pivoted to the outer end of a triparm fn; the inner end ofthis, arm being pivoted to the stud ci A spring f1 coiled about` thestud, c', and having one of its ends connected to the trip-arm f and theother end to the frame part 1, normally exerts its influence The resultof this construction is that each time the operator raises the trip-armf through the medium of the cam and link, so soon as the pin f7 ridesoff the cam which has raised it.` the trip arm f will be projectedquickly downwardly.

Located in the path of movement of the outer end of said trip-arm is apivoted pawl, f11,.pivoted at f1" preferably to the support e previouslyreferred to in line with thepawls e and e1 and above the cross-bar e* sothat when the trip arm f is operated in the manner described, the pawl fwill rock the cross-bar to release the motor mechanism in .ne mannerdescribed in connection with the pawls e and erl and trip arms c and c1.Extending laterally from the side of this pawl f is a pin, fa, Figs. l0and 11, and located in the path of movennt of this pin f, is a curvedarm, f1, com Lated at its upper end to a rock-shaft f located in saidsupport. Connected to the opposite end of this rockl shaft f is a curvedor cam-shaped projection f1". Projectimgl from the pawl e', which itwill be remembered is the pawl for closing the switch, is a laterallyprojecting pin f Figs. 10, 11 and 15 extending into the path of movementof the curve or camshape'd projection f1". The result of thisconstruction is that when the hand-operated trip-arm f is operated thepin f13 on the pawl, f, will strike the arm f, and rock the shaft f,swinging the cam-shaped projection]C16 inwardly and cause the pin f toride up the curved surface thereof and thus raise the pawl e to theposition shown in Fig. 10, in which position it will be out of the pathof movement of the trip-arm c2 so that when said trip-arm is operated atthe time set for turning on the lights the outer end thereof will missthe pawl e and thus leave the lights on. The rock-shaft f1 is fittedsnugly in the bearing so that when it is rocked, it will be held in thisposition by friction. I

In order to restore the pawl e again to o erative position upon thenextoperation, o the machine, I have provided a pivoted lever f, thelower end of which is adapted to be struck by a pin f1 (see Figs. 3 and5) extending laterally from the inner side of the arm d. This will causethe upper end of the lever f to strike the curvedarm f which is locatedin the path of movement ot the upper end of said lever, and thus rockthe shaft f1 in the op osite direction and permit the pawl e to rop backto its operative position.

Means are further provided for throwing the.pawl, e, out of commissioneverytime the switch is opened and for permitting the same to drop backinto operative position when the switch is closed; the pawl, e, beingthe one which is operated upon by the trip-arm c to open the switch andturn off the lights. Extending laterally from the outer end of the cam037, which, as before explained, is connected to and revolves with themotor shaft, is a pin f, adapted when the mechanism is operated to turnyoil the lights, to contact the lower end fn of a pivoted lever so as tocause the upper end )C22 of said lever to contact the rear end of thepawle; which projects beyond the pivotal' point of said pawl as shown inFig. 4, and thus raise said pawl to bring its outer end out of the pathof movement of the triparm c. The said pin f2 will hold the lever f21 inthis position until the next operation of the machine, whereupon thelever will be released and swing by gravit back to the position shown inFig. `5 an thus permit the pawl e'to swing back to its operativeposition. A si all pin f2 on the pawl, e, serves to `form 1 vtto tolimit its movement when swung on operative position by Winding mec/mismand cut-out dethe said lever.

aces. I have prei. ,led means for preventing the motor spring, d, fromrunning down to such an extent that it might tail to completely open theswitch at the time set for this operation so as toprevent any danger ofburning out the switch. from arcing. I accomplish this by providing forautomatically throwing out of operation certain of the tri ping devicesat the end ot a certain preetermined number of operations of themachine; as, for instance, at the end of the 20th operation. I alsofurther provide so that these tripping devices are thrown out ooperation upon a switch-opening movement of the mechanism so that therewill be no possibility of the switch being left closed for a periodlonger than the time set. I accomplish this in the following manner:Journaled in a suitable bearing on the frame part Q and also in abearing formed on the support e2 is a winding shaft, g, which has a gearor pinion g meshing with the large gear g2 secured to the barrel d;which surrounds the motor spring and to which one end of said spring isconnected. A ratchet g3 secured to the shaft and a pawl g* secured' tothe frame revents backward rotation o'f said shaft. gournaled in asuitable bearing' formed 0n the support e2 is a rock shaft gs whichcarries at one end an o erating lever, g6 (see Figs. 10 and l1 foretail) which lever has at one end a lateral projection 'gl adapted, whenthe winding shaft has been wound a certain number o revolutions, to bethrown into the path of a tooth gs on said shaft and thus lock the shaftfrom further movement, as indicated in Fig. 10. The normal position ofthe rock shaft and lever g is that shown in Fig. 11 and the parts willgo to this osition by gravity or otherwise when released by theoperating devices presently to be described.

Pivoted to the forward part of the s` port e2 is a lever g20 (see Figs.1 and 5) one arm 921 of which carries a cross-bar 922 which extendsunder the entire series of pawlse, e and fu. .(See Figs. 5, 10, 11 and15.)

Journaled to the frame part l beneath the shaft, g, is a star wheel gcarrying a 'laterally projecting pin glo and Ihave provided means forcausing said star wheel to make one complete revolution during theperiod of twenty operations of the machine referred to. Secured to themotor shaft d2 is a projecting tooth y adapted, at each completerevolution of said shaft, or every second operation of the mechanism, toengage the star wheel and move it one-tenth of a revolution.. Thisprojection g is pesiticned on the shaft de so that it will engage and.move the star wheel by that movement ot' the shaft d2 which is caused bythe tripping device which releases` the motor to open the switch so thatas before stated it willV be by one of these switch-opening movementsthat the pin g1 will be caused to engage the lle-wer end or tail of thelever g, which lies inthe path of movement of said pin. Thestar wheelwill be revolved by the motor shaft in the direction of the arrow shownin Fig. l] so that the pin g1 will strike the convex side of the lowerend of the lever g and rock the shaft g5 so as to cause the arm y on theopposite end of said shaft to contact a pin, g24 on the said lever y2"and rock said lever so as to cause the cress-bar g to lift all of thepawls, e, e`

and f, out of the path of movement of their respective trip-arms. c, cand f and effectually prevent any operation of the mechanism until themotor spring has been rewcund. A

F or the winding of the motor I have devised a key of specialconstruction and have also provided means whereby, after the key hasbeen inserted, it may not be Withdrawn until the motor has been fullyre-wound. In order to accomplish this I have provided for locking themotor shaft at a certain point. At each revolution of the winding shat't during the winding operation the tooth y thereon will engage thestar wheel and turn the same in the opposite direction from that inwhich it was turned by the motor shaft, or in the direction shown by thearrow in Fig. 10. If, therefore, the motor spring has become so fullyrun down that the pawls have been thrown out of commissionin the mannerdescribed5 it will be Seen that the star wheel will start from theposition shown in dotted lines in Fi 11 and so soon as it has beenturned su ciently the pin gm will strike the opposite side of the tailof the lever g as .shown in Fig. 10 and throw the projection (17 onsaid\ lever into the path of movement of the tooth g8 andl thus lock thewinding shaft g, from further revolution.

In order to insure the complete winding of tht motor I have providedmeans for locking the key to prevent its withdrawal until the completewinding of the motor has been accomplished. In Fig. 16 is shown thewinding key g12 which is one of special construction. As before stated,one end of the winding shaft is journaled in a bearing formed on thesupport e2, this bearing being represented by g13 in Figs. 14 and 15.The hearin g13 is projected a short distance beyond t e squared end ofthe winding shaft g and has pivoted thereto a key-lock g1* which whenthe key is inserted, falls down in the recess gli of said key andprevents its Withdrawal; the end of the key being formed with a beveledend 916 so that when the key is inserted the lock will be forced uwardly out of the way of the key but will all back by gravity into therecess g. A small housing y19 is formed on the support e2 in line withthe extended end y of the bearing and forms in effect a continuation ofthe same with a. slotted opening between them to receive the key-lock,as shown in Fig. 4. Secured to the viously described is a projectingfinger 917 adapted, when said shaft is rocked by the pin glo to lock thewinding shaft, t0 contact a projection g1g on said key-lock and swingthe same to the posit-ion shown in Figs. l() and 14 and thus release thekey. As this locking of the windin shaft does not take place until aftera pre etermined number of revolutions of said winding shaft, it will beseen that it will be impossible to withdraw s the key until the completenumber of desired revolutions of the wlndin j shaft have been given.Further, vit will winding of the motor will e seen that .the be uniform,slnce the star-wheel must be turned backwardly n by the winding shaftthe same distance that it has been turned forwardly by the motormechanism.

The motor shaft may be wound at any time except when the lights are on.devised means for lpreventing the winding of the motor while the lightsare on by providi ng a door for the key-hole, adapted to beautomatically locked when the' switch is closed and to be automaticallyunlocked when the switch is open. Th is door (/25 is connected to thelever g2" and is adapted to normally project over the key-hole asindicated in Fig. 5, but may be readily swung out. of the way by the thekey at all times except when the switch is closed. In order to preventthis door from being swung at such a time I have r0- vided on the cam dwhich 1s connecte to the motor shaft a projecting cach time the switchis close comes adjacent to the lower end of 'the lever 92 and preventsthe swinging of said lever in one direction, and a stop 927 extendingfrom the support e2 beneath the arm g prevents the swinging of the leverin the opposite direction.

In order to provide a buffer for the mechanism upon the operation ofclosing the switch. and also to assist the mechanism end of therock-shaft g5 pre- I have operator for the insertion of Y in g26 which,'11:

upon the opening of the switch, I have located on the base 7 aspring-pressed plunger h2, which telescopes into a. casing h and isnormally spring-pressed upwardly by a coilspring h2. (See Figs. 1 and2.) This plunger is adapted to be contacted b th.. movable member of theSwitch and a sorbs to a. large extent the shock when the movable memberis forced downwardly7 to close the switch. At the same time 1t assiststhe mechanism upon the opening operation and insures a quick break ofthe contacts 1n the event that the motor for any reason has run down tosuch an extent as might cause a sluggish action.
